After taking this supplement I became very nauseous, developed a fever higher than any time I've ever been sick, and puked more than I have when I contracted stomach flu or viruses in the past. I was out for the last two days and it was a horrible experience not worth any minor health benefits.
I don't usually write reviews for products but I felt it necessary that I tell people to be careful with this supplement. While laying sick in bed I did a lot of research on my phone, and apparently Spirulina and other blue-green algae absorbs the contaminants in its environment. So if there is animal waste or harmful bacteria in the environment that the Spirulina was cultivated in, it will absorb that and then go into your system when you take it.
Manufacturers try to downplay these experiences where other people have gotten sick (and yes there are others) as "detoxification." I suppose you are detoxifying yourself when you puke out the contents of your stomach 10 consecutive times in a row, and are lying in your bed nauseous, with a burning throat from all the stomach acid, pounding headache, and shivering from your fever.

Dont know if the product is good as I NEVER received it. I contacted them and all I got was a template answer. I kept writing them and all I got was the same answer, all copy paste. I lost my 65 dollars and my order. It has been 2 months and nothing. Very bad service and bad proficiency.
